There are two ways which we can use to change size of your MatDialog component in angular material
1) From Outside Component Which Call Dialog Component
import { MatDialog, MatDialogConfig, MatDialogRef } from '@angular/material';
dialogRef: MatDialogRef <any> ;
constructor(public dialog: MatDialog) { }
openDialog() {
this.dialogRef = this.dialog.open(TestTemplateComponent, {
height: '40%',
width: '60%'
});
this.dialogRef.afterClosed().subscribe(result => {
this.dialogRef = null;
});
}
2) From Inside Dialog Component. dynamically change its size
import { MatDialog, MatDialogConfig, MatDialogRef } from '@angular/material';
constructor(public dialogRef: MatDialogRef<any>) { }
ngOnInit() {
this.dialogRef.updateSize('80%', '80%');
}
use updateSize() in any function in dialog component. it will change dialog size automatically.
